Description
本創作係有關於一種緩衝結構,尤指一種應用於往復式氣動手工具緩衝避震用之氣動工具減震裝置。The present invention relates to a cushioning structure, and more particularly to a pneumatic tool damping device for use in a reciprocating pneumatic hand tool for cushioning shock absorbers.
按,氣動工具係一種利用高壓空氣作為工作動力源的往復式氣動手工具,習知之氣動工具,如第十四圖所示,包含:一握柄10、一氣閥單元20、一氣缸30、一活塞件40,其中該握柄10設有一供接設高壓空氣的進氣端101、一與該進氣端101相通之進氣通道102、一控制該進氣端101進氣之開關(圖中未示)及一筒狀部103,該筒狀部103內具有一沿軸向設置之腔室104,該腔室104與該進氣通道102相通,該氣閥單元20係設置於該筒狀部之腔室104內端部,該氣缸30一端穿入該筒狀部103之腔室104內結合固定,使該氣缸30與該氣閥單元20貼靠,該氣缸30內部設有一沿軸向設置之滑室301,另該氣缸30壁內於滑室301前端與氣閥單元20間設有一空氣流道302,藉由該空氣流道302使滑室301前端與氣閥單元20連通,該活塞件40容置於該氣缸30之滑室301內活動前後滑移。藉此,使用時開啟握柄10上的開關,使高壓空氣由握柄10之進氣端101經過進氣通道102到達筒狀部103腔室104內端部的氣閥單元20,透過該氣閥單元20控制高壓空氣由氣缸30之滑室301後端進入,推動活塞件40往前滑動位移至預定位置撞擊 工具頭(圖中未示),受該工具頭擋止而停止滑動,接著高壓空氣經氣閥單元20控制變換由空氣流道302進入氣缸30滑室301前端,推動活塞件40往後滑動位移撞擊氣閥單元20,受該氣閥單元20擋止而停止滑動,如此,往復前後推動活塞件40,進行預定的工作。According to the pneumatic tool, a reciprocating pneumatic hand tool using high-pressure air as a working power source, as shown in FIG. 14, includes: a handle 10, a gas valve unit 20, a cylinder 30, and a pneumatic tool. The piston member 40, wherein the handle 10 is provided with an intake end 101 for connecting high-pressure air, an intake passage 102 communicating with the intake end 101, and a switch for controlling the intake of the intake end 101 (in the figure) And a cylindrical portion 103 having an axially disposed chamber 104 therein, the chamber 104 communicating with the intake passage 102, the valve unit 20 being disposed in the tubular shape At the inner end of the chamber 104, one end of the cylinder 30 penetrates into the chamber 104 of the cylindrical portion 103, and the cylinder 30 is abutted against the valve unit 20, and the cylinder 30 is internally provided with an axial direction. a sliding chamber 301 is disposed, and an air flow passage 302 is disposed between the front end of the sliding chamber 301 and the gas valve unit 20 in the wall of the cylinder 30. The air flow passage 302 connects the front end of the sliding chamber 301 with the gas valve unit 20. The piston member 40 is accommodated in the sliding chamber 301 of the cylinder 30 to move back and forth. Thereby, the switch on the handle 10 is opened during use, so that the high-pressure air passes through the intake passage 101 of the grip 10 through the intake passage 102 to the valve unit 20 at the inner end of the chamber 104 of the cylindrical portion 103, through which the gas passes. The valve unit 20 controls the high pressure air to enter from the rear end of the sliding chamber 301 of the cylinder 30, and pushes the piston member 40 to slide forward to a predetermined position. The tool head (not shown) is stopped by the tool head to stop sliding, and then the high-pressure air is controlled by the air valve unit 20 to enter the front end of the cylinder 30 of the cylinder 30 by the air flow passage 302, and the piston member 40 is pushed to slide backward. The impingement valve unit 20 is stopped by the valve unit 20 to stop sliding, so that the piston member 40 is pushed back and forth before and after the reciprocation to perform a predetermined operation.
然該習知氣動工具,推動活塞件40往後滑動位移撞擊氣閥單元20時,會產生反作用力傳遞至使用者手部,如此,在活塞件40不斷的往復前後滑動位移過程中,不僅使用者需費更大的力氣握持該氣動工具,並且容易有手痠不舒服的情況,甚至會對使用者手部關節造成傷害。However, when the conventional pneumatic tool pushes the piston member 40 to slide back and collide against the valve unit 20, a reaction force is transmitted to the user's hand. Thus, during the sliding movement of the piston member 40, the sliding member is not only used. It takes a lot of effort to hold the pneumatic tool, and it is easy to have unsatisfactory hands and even cause damage to the user's hand joints.
為改善上述缺失,乃有業者開發出於筒狀部之腔室內設置單一彈簧,藉由該單一彈簧於活塞件40往後滑動位移撞擊氣閥單元20時,達到緩衝減震效果,降低反作用力傳遞至使用者手部。惟,該單一彈簧的彈力有限且易有彈力不平均的情形,因而緩衝減震效果不佳,無法有效降低氣動工具使用時產生的反作用力傳遞至使用者手部。In order to improve the above-mentioned defects, a manufacturer has developed a single spring for the chamber of the cylindrical portion. When the single spring is slidably displaced against the valve unit 20, the cushioning effect is reduced and the reaction force is reduced. Passed to the user's hand. However, the single spring has limited elastic force and is easy to have uneven elastic force, so the buffer damping effect is not good, and the reaction force generated when the pneumatic tool is used cannot be effectively reduced to the user's hand.
本創作人有鑑於習知氣動工具,於筒狀部之腔室內設置單一彈簧,所產生的緩衝減震效果不佳,是以乃思及創作的意念,經多方探討設計與試作樣品試驗,及多次修正改良後,終設計出本創作。In view of the conventional pneumatic tools, the creator has a single spring in the chamber of the cylindrical portion, and the cushioning and shock absorption effect is not good, and the design and trial sample test are discussed by many parties with the idea of creating and thinking. After many revisions and improvements, I finally designed this creation.

Further, the plurality of buffer springs 5 are separated and positioned.
再者,該複數緩衝彈簧5除可如上述利用複數第一定位部123及複數第二定位部212加以定位外,另亦可如第十圖、第十一圖、第十二圖及第十三圖所示,於該套筒12腔室120之封閉面121與該氣缸2滑動套21之抵靠部211間設置複數定位套筒6,藉由該複數定位套筒6將該複數緩衝彈簧5分隔定位,並且得以限制緩衝彈簧5的最大壓縮,延長緩衝彈簧5的使用壽命。Furthermore, the plurality of buffer springs 5 can be positioned by using the plurality of first positioning portions 123 and the plurality of second positioning portions 212 as described above, and can also be as shown in the tenth, eleventh, twelfth and tenth In the three figures, a plurality of positioning sleeves 6 are disposed between the closing surface 121 of the sleeve 12 chamber 120 and the abutting portion 211 of the sliding sleeve 21 of the cylinder 2, and the plurality of damping springs are used by the plurality of positioning sleeves 6. 5 separate positioning, and can limit the maximum compression of the buffer spring 5, extending the service life of the buffer spring 5.
由上述具體實施例之結構,可得到下述之效益:本創作氣動工具緩衝墊結構,其氣動工具本體1套筒12之腔室120中設置複數緩衝彈簧5,該複數緩衝彈簧5排列彈抵於該套筒12腔室120之封閉面121與該氣缸2滑動套21之抵靠部211間,使該封閉面121與該抵靠部211間形成複數彈性支撐點,而可於活塞件4往後滑動位移撞擊氣閥單元3時,藉由該複數緩衝彈簧5平均分散緩衝撞擊的反作用力,形成多重緩衝避震效果,有效降低反作用力傳遞至使用者手部,達到使用操作省力及保護使用者手腕減輕痠痛及傷害的效果。According to the structure of the above specific embodiment, the following benefits can be obtained: the air tool cushion structure of the present invention is provided with a plurality of buffer springs 5 in the chamber 120 of the sleeve 12 of the pneumatic tool body 1 , and the plurality of buffer springs 5 are arranged to be slid Between the closed surface 121 of the sleeve 12 chamber 120 and the abutting portion 211 of the sliding sleeve 21 of the cylinder 2, a plurality of elastic supporting points are formed between the closing surface 121 and the abutting portion 211, and the piston member 4 can be formed. When the rear sliding displacement impacts the valve unit 3, the complex buffer spring 5 uniformly disperses the reaction force of the buffering impact to form a multi-buffering shock-absorbing effect, effectively reducing the reaction force transmission to the user's hand, achieving labor saving and protection. The user's wrist reduces the effects of soreness and injury.
綜上所述,本創作確實已經達於突破性之結構,而具有改良之創作內容,同時又能夠達到產業上利用性與進步性,當符合專利法之規定,爰依法提出新型專利申請,懇請 鈞局審查委員授予合法專利權, 至為感禱。In summary, this creation has indeed reached a breakthrough structure, and has improved content of creation, while at the same time achieving industrial use and progress. When complying with the provisions of the Patent Law, it proposes a new type of patent application according to law. The ruling board examiner grants legal patent rights, To the pray.
